3″ Downpipe with 100 CPI High Flow Catalytic Converter and ultra-slim flex section. This is a great choice for the Ecoboost Mustang owner who wants increased performance but doesn’t want to go completely catless. The 100 CPI (cells per inch) metal substrate catalytic converter dramatically increases exhaust flow over the restrictive OEM catalytic converter. This is definitely one of the first mods that you should do if you are looking to get the most power out of your Ecoboost Mustang and want to have a catalytic converter.
